Figure 4

(a, e) Gate voltage sweeps at constant drain current for LEFETs with short and long Au NRs, respectively. The applied voltages at which EL images in (b) and (f) were acquired are indicated (1–5). (b, f) Representative EL images show the movement of the emission zone and intensity increase due to coupling with Au NRs (4, 5 vs 1, 2). (c, g) Cumulative maximum EL intensity maps for LEFETs with short (c) and long (g) Au NRs. (d, h) Wavelength-dependent EL intensity enhancement factors for short (d) and long (h) Au NRs at drain current of 3 μA. The scale bar for (b, c, f, g) is 30 μm.
